My little guy Volker just scared the stuffing out of me. I glanced over at my tank to see him laying compleatly on his side and not moving. A moment later he zoomed up to flare at his neighbor, but now he's listing to one side pretty heavly when he's not moving in the water. When he's swimming he's fine and stright, but when he's not he start to roll a bit.

I JUST was out today buying new foods too-- I bought two new pellets and fed all my guys two of each kind. I bought Omega one Betta Buffet pellets and Topfin Color Enhancing Betta Bits, since both have 2 kinds of meats as their first ingredients. I'm not sure if they caused it or not-- they are a bit bigger than the rest of the pellets I have, and I don't recall Volker listing before. I'm going to post the list of questions and answers in my next post.

It just makes me nervious. Previously I had 3 foods + bloodworms. New Life Spectrum Betta formula for most days, Aqueon betta food pellets, and bettamin flakes, + frozen bloodworms, and I normally just rotate what I feed daily. (so one day it one type of food). Now I've got one different food for every day of the week. I plan on dropping the flakes out eventually for a different frozen food, next time I go shopping, so that they're getting frozen 2 out of 7 days of the week.

Well then, I've never tried feeding a different food every day. Variety is good but wouldn't feeding a different pellet every day give him some constant indigestion and etc? IMO that isn't the best plan... I'm not sure if feeding so many different foods is beneficial or detrimental... I prefer having 1 or 2 staple pellets and changing up the frozen foods. Pellets in the AM, frozen in the PM.

hmmm well I could always switch to making NLS a main one, and feed like 2 of that plus rotate one of the others every day then. I'd been told that more varity was better, and to look for ones that have meats as at least their first 2 ingredients, and so that's what I've been collecting. All the other fish seem pretty fine though.

Variety is good, I'm just concerned that "too many" different ones might make cause some digestion issues. I don't know though. If the other bettas are handling it fine then you can continue with them, but you might want to be more careful with the one.
